Hydrating or oxidizing process using a metal-containing, shaped organosiloxane amine copolycondensate catalyst

Abstract

Shaped organosiloxane amine copolycondensates are described which contain Pd, Pt, Ru and/or Rh, as well as optional promotors and/or moderators. The shaped copolycondensate function as a carrier for metals and are made up of units of: ##STR1## and/or units of Y--R 6 . R 2 to R 6 are a group represented by the formula: ##STR2## wherein R 7 is a group bound to N, X, or Y (for example, an alkylene group) and R 1 is R 7 --SiO 3/2 , H, CH 3 , C 2 H 5 , or C 3 H 7 . X stands for a double-bonded group such as --S--, --S 2 --, --S 3 --, --S 4 --, --HN--CS--NH-- and Y stands for a monovalent groups such as --CN, --SCN, --SH, --S--CH 3 , --NH 2 , --NH--(CH 2 ) 2 --NH 2 . The carrier substance may be cross-linked with cross-linking agents containing Si, Ti, Zr or Al. The metal-containing product is spherical in form and is defined by the parameters of sphere diameter, specific surface and pore volume as well as bulk density. Methods of production and use of the copolycondensates are also described.
